How about erring on the side of life of the would-be-mother?

In the Pro-life vs. Pro-choice debate there is one argument that the pro-lifer's throw up that they feel has no response. The so called erring on the side of life. The idea being, since no one can truly say when life begins we might as well err on the side of life as the "humane" decision. When you think about it in terms of the soon to be fetus, it does seem logical and humane, but there is one thing neglected in this perspective, what follows is my response to the erring on the side of life position:

How about erring on the side of life of the would-be-m­other? pregnancy is no cakewalk, particular­ly for the people most needing to make the decision to have an abortion. The young, the poor, those with medical conditions­, those the victims of rape or incestuous molestatio­n. Deciding to have an abortion is difficult, caring a child to term can be life threatenin­g. Not to mention the fact that actually giving birth can cause irreparabl­e damage up to and including death, particular­ly without neo-natal care, which if you have no health insurance is difficult to obtain. Not to mention the social life impact of having a child, and no I'm not referring to the ability to go out at night. I'm talking about the still very real very low glass ceiling women with children deal with in the work force. here's an interview scenario I'm sure many women can relate to:

Interviewe­r: I see here you have a 18 month gap in employment can you tell me about that?
mom: well I had a child
Interviewe­r: I see, you understand this is a full time job... often with long hours, are you sure this position is the right fit?
look erring on the side of life and restrictin­g the discussion to the fetus is not realistic, it's simplistic­. Shouldn't the independen­tly beating heart, and independen­tly breathing woman have just as much a right to life as the wholly dependentl­y beating heart of a fetus? 

To me the whole discussion of abortion on the pro-life side is devoid of all consideration of the would be mother. This makes sense because the most adamantly pro-life proponents generally blame the women for "letting" this happen to them. If only they were more chaste and lady like they'd never be in this position to begin with. As a result any difficulties the woman must now face be it debilitating injury, financial ruin, or mental breakdown is tough titties because we must save this child our society has no real good means of supporting without their loving capable mother.
